Visão Geral
Description
UCC23525CDWYR is a Texas Instruments isolated gate-driver IC (UCC family) used to drive power MOSFETs/IGBTs in isolated switch-mode power supplies, motor drives, and inverters. It provides galvanic isolation between the control logic and the power side, and delivers a high-current gate drive for fast switching, along with protections (e.g., undervoltage lockout, fault/diagnostic outputs) typical of TI drivers. The CDWYR suffix indicates a specific package/date-code variant. For exact electrical specs (isolation rating, supply ranges, drive strength, timing), consult TI’s datasheet on ti.com. If you want, I can pull and summarize the key figures.
Features
UCC23525CDWYR is a high-voltage primary-side regulation (PSR) controller for isolated flyback SMPS. Key features:
- Opto-free PSR feedback for easier isolation
- Valley switching for improved efficiency
- Universal input range
- External MOSFET drive (no integrated FET)
- Fixed-frequency operation with soft-start
- Protections: overcurrent/short-circuit, overvoltage/brown-out, thermal shutdown
- Enable pin
- RoHS-compliant, 8-pin package (CDWYR)
